To assess visual processing and balance and their relationship to each other in ambulatory children with CP.
Case series that compares a group of subjects with CP and a control group in regard to visual processing and balance. Duration for participant is one visit.
Patients at Shriners Children's Chicago.
CP group has five participants with a diagnosis of CP, who were able to ambulate without an assistive device (GMFCS II), and all have visual perception issues. The five typically developing participants in the Control Group were age matched, and have normal GMFCS level. Participants' age 7-17yo.
Each participant was asked demographic questions and completed multiple tests: TVPS-4, PBS, and SOT.
Main Outcome Measures
Test of Visual Perceptual Skills - 4th Edition was used to assess visual-perceptual strengths and weaknesses using black and white drawings and multiple-choice responses. Pediatric Balance Scale assesses functional balance skills in school-aged children who are able to stand on their own by asking them to complete balance tasks in sitting and standing. The Sensory Organization Test (SOT) on the CPD tests the participants under six balance conditions with the child wearing a harness and standing on a balance platform.
A paired t-test was run for the three outcome tools between the participant groups. A statistically significant difference was found between the CP and Control Groups for the TVPS-4 (p = 0.022).. Using Pearson correlation, there was an association between age of independent walking (mos.) (r=0.84) and comfort duration with reading (r=-0.99) for the CP group. All the children with CP in the study have visual perception issues, but 3/5 have a normal balance score on PBS, and 4/5 have issues with reading.
A clear conceptual definition and framework for measuring vision skills is critical in furthering our understanding of the topic. Tracking skills were not tested in this study, but could affect reading and balance. Could test dynamic balance and tracking skills to understand vision in balance in children with CP.
